In four years, let's have a debate where the candidates may if they want have a computer and access to the Internet. This would allow the candidates to post pointers to things that viewers could read while listening to the debate.
By then most of us will be two-screen TV watchers. Why not let the debate happen on the second screen as well.
I know this will seem like a radical idea, but in 2008 they were still time-delaying debates so people on the west coast saw them three hours after the east coast. There were probably just a few thousand people commenting on the debates in real-time. Now, what a difference. We've covered a lot of distance in just four years.
